Indentation, owing to its ability to induce permanent deformation in a controlled manner
even in highly brittle materials that are otherwise not amenable to critical mechanical testing …

Prior to macroscopic yielding, most materials undergo a regime of plastic activity that cannot
be resolved in conventional bulk deformation experiments. In this pre-yield, or micro-plastic …

Microstructural heterogeneity is an important issue in understanding the mechanical and
physical properties of metallic glasses (MGs). Theoretically, physical aging below the glass …

The studies on dynamics and deformation in glassy materials are particularly challenging
because of their strongly disordered atomic structure. Here, by probing the changes in the …

Plastic flow in metallic glasses (MGs) is known to be mediated by shear transformations
(STs), which have been hypothesized to preferentially initiate from identifiable local “defect” …

The existence of an indentation size effect (ISE) in the onset of yield in a Zr-based bulk
metallic glass (BMG) is investigated by employing spherical-tip nanoindentation …

Thermally activated deformation is investigated in two metallic glass systems with different
cooling histories. By probing the atomic displacements and stress changes on the potential …

Suppressing crystallization of a metallic melt results in a disordered solid, also known as a
metallic glass. One may conclude that a metallic glass is free of defined structural length …

It has been well documented that plastic deformation of crystalline and amorphous
metals/alloys shows a general trend of “smaller is stronger”. The majority of the experimental …

The nanoindentation technique was employed to examine the strain rate sensitivity, m, and
its dependence on the structural state of a Zr-based bulk metallic glass (BMG). The free …
